Step-by-step explanation:
none of the above are correct
The answer for this problem is that x = 60°, or B.
We can solve this problem by using our knowledge of quadrilaterals. In this problem, we need to know that the number of degrees in a quadrilateral is equal to 360, but, the formula to find the number of degrees in a polygon with n sides is (n-2) * 180.
Now that we know that the sum of the angles if 360°, we can add all the angles and solve for x. The angles with the squares are 90°.
2x° + x° + 90° + 90° = 360°
Get x by itself, combine like terms.
3x° + 180° - 180° = 360° - 180°
3x° = 180°
x = 60°, or B.
Hello there.
<span>There were 196 students that participated in a clean-up event at a nearby lake. this is one fourth of the entire student population. write and solve an equation to find the number of students at this school.
Answer: x is the number of students in the school.
</span>

= 196.
<span>196 x 4 = 784.
Therefore the number of students in this school is
784.
Hope This Helps You!Good Luck Studying ^-^</span>
Answer:
The estimate of the population proportion of defective battery is 0.1333.
Step-by-step explanation:
Estimate of the population proportion of defective battery:
The estimate of the population proportion is the sample proportion.
Sample proportion:
Number of desired outcomes divided by the number of total outcomes.
Proportion of defective battery:
20 defective out of 150. Thus:

The estimate of the population proportion of defective battery is 0.1333.
Y = 3. 3 is the y coordinate for the point with an x coordinate of -1 that lies on the line with a negative reciprocal to line ST.
